Citrus limonoids induce apoptosis and inhibit the proliferation of pancreatic cancer cells.

Food & Function, 2021
In our recent study, we demonstrated that certain limonoids isolated from citrus seeds induced apoptosis in human pancreatic (Panc-28) cells. In this study, limonin, nomilin and limonexic acid (LNA) were investigated for understanding the possible mode ...

Limonoids of Teclea ouabanguiensis

Journal of Natural Products, 1986
The stem bark of Teclea ouabanguiensis has yielded six triterpenoids, two of which are new. The known compounds were identified spectroscopically as 7-deacetylazadirone (2), 7-deacetylproceranone (3), tecleanin, (4), and lupeol. The novel compounds include the tetranortriterpenoids, 7-deacetoxy-7-oxoazadirone (1), and ouabanginone (5).

limonoids from Khaya senegalensis

Phytochemistry, 1998
A new limonoid was isolated from the bark of Khaya senegalensis and identified as 2,6-dihydroxyfissinolide. The assignments of some signals in the (13)C NMR spectrum of fissinolide have been reversed and the signals of the (1)H NMR spectrum of methyl 3beta-acetoxy-6-hydroxy-1-oxomeliac-14-enoate have been assigned.

Phragmalin Limonoids from Chukrasia tabularis

ChemInform, 2004
Six phragmalin limonoids, named tabulalin and tabulalides A-E, were isolated from the root bark of Chukrasia tabularis (Meliaceae). Their structures were determined by spectroscopic methods, and their antifeedant properties evaluated.

Limonoid biosynthesis 3: Functional characterization of crucial genes involved in neem limonoid biosynthesis

Phytochemistry, 2021
Neem (Azadirachta indica L.) is well known for its medicinal, agricultural, and pesticidal applications since ages. The secondary metabolites, limonoids, confer these biological properties, wherein over 150 different limonoids have been reported from neem.

Limonoids from Azadirachta excelsa

Phytochemistry, 1998
Activity-directed fractionation of a stem extract of Azadirachta excelsa using KB (human oral epidermoid carcinoma) cells led to the isolation of four meliacin-type limonoids. Two of these constituents were novel, namely, 2,3-dihydronimbolide and 3-deoxymethylnimbidate, and these were purified along with the known compounds, nimbolide and 28 ...

A limonoid from Trichilia estipulata

Phytochemistry, 2000
The limonoid 21,24,25,26,27-pentanor-15,22-oxo-7alpha,23-dihydroxy-apotirucalla(eupha)-1-en-3-one was isolated from the dichloromethane extract of the stem bark of Trichilia estipulata. Its structure was established by spectroscopic methods (UV, EIMS, 1H and 13C NMR, HMQC and HMBC).
